Sigmund Freud 
A Young Girl’s Diary 

THE best preface to this journal written by a young girl belonging to the upper middle class is a letter by Sigmund Freud dated April 27, 1915, a letter wherein the distinguished Viennese psychologist testifies to the permanent value of the document: “ This diary is a gem. Never before, I believe, has anything been written enabling us to see so clearly into the soul of a young girl, belonging to our social and cultural stratum, during the years of puberal development. We are shown how the sentiments pass from the simple egoism of childhood to attain maturity; how the relationships to parents and other members of the family first shape themselves, and how they gradually become more serious and more intimate; how friendships are formed and broken. We are shown the dawn of love, feeling out towards its first objects. Above all, we are shown how the mystery of the sexual life first presses itself vaguely on the attention, and then takes entire possession of the growing intelligence, so that the child suffers under the load of secret knowledge but gradually becomes enabled to shoulder the burden. Of all these things we have a description at once so charming, so serious, and so artless, that it cannot fail to be of supreme interest to educationists and psychologists.’
